Recently, biodiversity loss has become direr international. Human behavior is one of the causes that harm the biodiversity richness. Malaysia which is known as the megadiversity country also facing with the similar problem. Conservation of the biodiversity must be taken seriously and importantly by people to maintain the relationship between human and nature because we are affecting each other. Thus, this research was aiming to evaluate the relationship between human attitude, experience and knowledge toward the awareness of biodiversity conservation. The research was conducted using 4 variables from Ajzen’s Theory of Planned Behavior (TPB) which are behavior, perceived behavioral control, subjective norms and attitude. This study was carried out in Malaysia by conducting a survey of 30 students from a private university. The findings of this study indicate that the mentioned have given the positive effect to the awareness of biological diversity conservation. In addition, the relation of knowledge and attitude also show the great correlation between themselves. Therefore, knowledge, experience and attitude are the factors that could increase peoples' awareness towards the biodiversity conservation and knowledge is the greatest influence in creating peoples' awareness.
Essential oil extracted from Melaleucagenus has been widely used worldwidefor many purposes. Most of the its has been reported as the source of phytochemical compound where mostly have anti-inflammatory, antiulcer, antioxidant, antimicrobial and insecticide properties. Thus, three objectives that have been highlighted in this study are (1) to extract essential oil (cajuput oil) from fresh leaves of MelaleucacajuputiPowell using simple steam distillation,(2) to determine the chemical components of MelaleucacajuputPowell essential oil using GCMS and (3) to compare the chemical compound and its percentage with the previous study.Results found that there were 41 chemical compounds that have been identified. The chemical compounds were monoterpenes such as α-terpinolene, α-pinene, sabinene, 4-terpineol and γ-terpinene. The highest chemical compounds found were caryophyllene (20.16%), α-terpinolene (17.0%),α-humulene (11.91%), βelemene (7.62%) and γ-terpinene (5.62%). In previous research, 1,8-cineole chemical compound was foundhowever, in this study a different chemical compound found, it was caryophyllene, this is due to different geographic area.As a conclusion, most of the compounds found was aromatic, antibacterial andinsecticide properties.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
